Title:
METHOD FOR PREPARING 3-HYDROXYPROPIONIC ACID THROUGH TWO STEPS
Document Type and Number:
WIPO Patent Application WO/2022/025710
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing 3-hydroxypropionic acid (3-HP) and/or a method for improving the productivity of 3-HP, the methods comprising the steps of: performing high-concentration cell culturing of a 3-HP-producing strain; and (2) isolating high-concentration-cultured cells to inoculate a medium for 3-HP production with same, thereby producing 3-HP, and thus the present invention can improve the productivity and yield of 3-HP.
